PatternScaleBehavior enum

Changes how the pattern is drawn on the Canvas shape or Widget. Used in the paintOn methods of each Pattern.

All patterns are by default scaled to their container (PatternScaleBehavior.container). This means that, regardless of its size, a Rectangle will contain 40 diagonal stripes or 40 dots.

Use PatternScaleBehavior.canvas to scale the pattern to the whole Canvas area. Now the Canvas will contain 40 diagonal stripes or 40 dots, so, a Rectangle will contain as many dots or stripes as it can fit.

Pattern p = DiagonalStripesThick(bgColor: bgColor, fgColor: fgColor);
p.paintOnRect(canvas, size, rect1, patternScaleBehavior: PatternScaleBehavior.canvas);

Use PatternScaleBehavior.customRect and a customRect (e.g. a Rectangle with half the Canvas height) to further customize the Pattern size:

Rect halfCanvas = Rect.fromLTWH(0, size.height / 2, size.width, size.height / 2);
p.paintOnRect(canvas, size, rect1, patternScaleBehavior: PatternScaleBehavior.customRect
, customRect: halfCanvas);
